Aortofemoral surgery and sexual function

Area of Science:

• Vascular Surgery
• Urology
• Cardiovascular Medicine

Background:

• Aortoiliac occlusive disease (AIOD) is a significant cause of peripheral artery disease.
• Erectile dysfunction (ED) is a common comorbidity in patients with AIOD, impacting quality of life.
• The pathophysiology of ED in AIOD and the impact of surgical interventions on erectile function (EF) require further elucidation.

Purpose of the Study:

• To determine the incidence and pathophysiology of ED in patients with AIOD.
• To evaluate the effects of aortofemoral surgery, specifically endarterectomy (E) and reconstruction (R), on EF.
• To compare the efficacy of endarterectomy versus reconstruction in improving or maintaining EF.

Main Methods:

• Prospective evaluation of 31 male patients undergoing aortofemoral surgery.
• Assessment of erectile function (EF) using questionnaires and penile dynamic Colour Doppler Ultrasonography before and 3 months post-surgery.
• Categorization of ED causes into arteriogenic, venogenic, combined, and neurogenic components.

Main Results:

• Eighty-four percent (26/31) of patients with AIOD presented with ED.
• The primary causes of ED were combined arteriogenic and venogenic (53%), purely venogenic (23%), neurogenic (16%), and purely arteriogenic (8%).
• Post-surgery, 7 out of 20 evaluated patients showed improved EF; 6 of these had undergone endarterectomy (E), while only 1 had reconstruction (R).

Conclusions:

• The majority of patients with AIOD suffer from ED, with both reduced penile arterial inflow and veno-occlusive dysfunction contributing significantly to its pathophysiology.
• Atherosclerosis in AIOD may also impair the penile veno-occlusive mechanism.
• Endarterectomy appears to be a more favorable surgical option than reconstruction for improving or preserving erectile function in patients with AIOD.
